there are 40 markers in a bag. of the 10 scented markers, 6 are permanent markers. half of the unscented markers are erasable. which two - way table is correct?

Answer

Answer:

The first two - way table is correct.

Explanation:

Step1: Calculate number of unscented markers

Total markers = 40, scented markers = 10, so unscented markers = 40 - 10=30.

Step2: Calculate scented erasable markers

Scented markers = 10, scented permanent markers = 6, so scented erasable markers = 10 - 6 = 4.

Step3: Calculate unscented erasable and permanent markers

Half of unscented markers are erasable, so unscented erasable markers = $\frac{30}{2}=15$, and unscented permanent markers = 15.

Step4: Calculate totals

Permanent markers: 6 + 15=21. Erasable markers: 4 + 15 = 19. Total scented: 10, total unscented: 30, total markers: 40. This matches the first two - way table.
